[0044] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0045] As described in the background art, the housing assembly is an important component of household appliances such as air conditioners or heat pump outdoor units. The housing includes a connected housing and a grille. The grille is usually set on the housing and located in front of the housing air outlet to block the air outlet and to change the air outlet direction.

[0046] To improve the overall aesthetics of the housing assembly, the grille is usually integrated into one piece. Part of the grille covers the air outlet of the housing, while another part covers the maintenance panel, resulting in a large area and volume for the grille, and making its manufacturing more difficult. Furthermore, due to the large area and volume of the grille, it is usually necessary to use fixing clamps or similar devices to position and install it, thus complicating the grille installation process.

[0047] To address the aforementioned technical problems, this application provides a housing assembly and a household appliance. The housing assembly has multiple interconnected grilles on the front side of the front panel assembly, allowing the multiple grilles to be processed and manufactured separately, thereby reducing the processing difficulty of the grille assembly.

[0048] When assembling the housing components, multiple grilles can be detachably installed on the front side of the corresponding panel, and the multiple grilles are located in the same plane. This reduces the overall volume and installation difficulty of the grilles by installing multiple grilles separately, thus making the process of installing the grilles into the housing simpler.

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] The technical solutions of this application and how they solve the aforementioned technical problems are described in detail below with specific embodiments. These specific embodiments may exist independently or in combination with each other. Identical or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0051] Reference Figure 1 and Figure 2 This application provides a housing 100 assembly, including a housing 100, the inner side of which can be used to house structures such as fans.

[0052] The housing 100 may have a front panel assembly, which may be provided with an air outlet 111. The front panel assembly is a functional surface of the housing 100, and through the provided air outlet 111, it can perform the function of airflow outward.

[0053] The front panel assembly may include multiple panels, which may be connected in the same plane.

[0054] The front panel assembly may include a first panel 110 and a second panel 120 connected to each other. Both the first panel 110 and the second panel 120 may be arranged facing forward. The first panel 110 and the second panel 120 may be located in the same plane. An air outlet 111 is provided in the first panel 110 so that the fan can exhaust air through the air outlet 111 of the first panel 110.

[0055] For example, the first panel 110 can be used to enclose and shield the fan, so as to provide a certain protection for the fan. The second panel 120 can be set as a maintenance panel, and the second panel 120 can be provided with a maintenance port, which can communicate with the interior of the housing 100, so that the internal structure of the housing 100 can be repaired or replaced through the maintenance port.

[0056] Both the first panel 110 and the second panel 120 face the front of the housing 100. A mounting component can be provided between the first panel 110 and the second panel 120, which can be used to install subsequent structures such as the first grille 200 and the second grille 300. Alternatively, the first panel 110 and the second panel 120 can be smoothly transitioned, making the overall structure of the housing 100 more aesthetically pleasing.

[0057] Reference Figure 1 and Figure 2 In some possible implementations, the housing 100 assembly may include a grille assembly. The grille assembly may be positioned over the front of the front panel assembly. The grille assembly can be used to prevent foreign objects from entering the device and to optimize airflow paths.

[0058] The grille assembly may include multiple grilles. These grilles can be connected in the same plane to cover the front side of the front panel assembly. Each panel may have at least one grille. The grilles can be specifically designed for different panel areas; for example, the grille at the air conditioning vent 111 may have a large aperture to ensure high airflow, while the grille at the air conditioning circuit board may have a small aperture to balance heat dissipation and dust prevention.

[0059] In some possible implementations, the grille assembly may include two sets of grilles. The first set of grilles 400 may extend in a straight line, and the second set of grilles 500 may extend in a ring shape. For example, the grille located at the air outlet 111 may be the second set of grilles 500. Since the air outlet 111 is generally designed to be circular, the grille covering the air outlet 111 may be designed to extend in a ring shape. The grilles covering other panels besides the air outlet 111 may be the first set of grilles 400, and the grilles may extend in a straight line vertically, horizontally, or obliquely.

[0060] In some possible implementations, the grille assembly may include a first grille 200. The first grille 200 is detachably disposed on the front side of the first panel 110, and at least a portion of the first grille 200 may cover the air outlet 111 to shield and protect the air outlet 111.

[0061] For example, the first grille 200 may be provided with multiple air guides 210, all of which are connected to the air outlet 111 of the housing 100, so that the airflow from the air outlet 111 can be blown out through the multiple air guides 210. This allows the air outlet direction of the household appliance (e.g., a heat pump, which will be used as an example in the following text) to be changed by the first grille 200, and the airflow at different positions of the air outlet 111 can be made more uniform.

[0062] In the first grille 200, multiple air vents 210 can exhaust air in the same direction. Alternatively, multiple air vents 210 can exhaust air in multiple directions, allowing the airflow from the heat pump fan to be blown out in different directions through the air outlet 111 and the multiple air vents 210, thereby making the airflow direction of the heat pump more diversified.

[0063] In some possible implementations, the housing 100 assembly may include a second grille 300. The second grille 300 is detachably disposed on the front side of the second panel 120, and the second grille 300 is located in the same plane as the first grille 200.

[0064] By adopting the above technical solution, the housing 100 assembly of this application embodiment, by setting a cooperating first grille 200 and second grille 300, such that the first grille 200 and second grille 300 are respectively disposed on the first panel 110 and the second panel 120 of the housing 100, and the first grille 200 and second grille 300 are located in the same plane, so that the first grille 200 and second grille 300 can be processed and manufactured separately, thereby reducing the processing difficulty of the first grille 200 and second grille 300.

[0065] Reference Figure 1 and Figure 2 ,as well as Figure 3 and Figure 7 Multiple grilles can be detachably connected.

[0066] For example, the first grille 200 and the second grille 300 can be detachably connected, so that the first grille 200 and the second grille 300 can be relatively fixed, the connection between the first grille 200 and the second grille 300 is more stable, and the interconnection of the first grille 200 and the second grille 300 can also make the structure of the housing 100 assembly more aesthetically pleasing.

[0067] It should be noted that since both the first grille 200 and the second grille 300 have openings such as air guide 210, their overall structures are quite similar. The extending direction of the air guide 210 of the first grille 200 and the air guide 210 of the second grille 300 can both be set parallel to the second direction, and the width of the air guide 210 of the first grille 200 and the air guide 210 of the second grille 300 can also be set to be the same.

[0068] When the first grille 200 and the second grille 300 are connected, a splicing seam extending along the second direction will be formed between the first grille 200 and the second grille 300. Since both the first grille 200 and the second grille 300 have air guides 210, the structure of the splicing seam can be similar to the shape of the air guides 210, so that the splicing seam can be hidden between the air guides 210, making the structure of the first grille 200 and the second grille 300 more aesthetically pleasing.

[0069] Reference Figure 1 and Figure 2 ,as well as Figure 3 and Figure 7 In some possible implementations, the first grille 200 may be provided with a insertion groove 230 facing the first panel 110, and the insertion groove 230 may extend in a second direction. The second grille 300 is provided with a connector 320, which can be inserted and engaged with the insertion groove 230.

[0070] When the second grille 300 is fixed to the second panel 120, the connector 320 is inserted into the connector slot 230 along the second direction, so that the second grille 300 is fixed to the first grille 200.

[0071] It should be noted that the insertion slot 230 can be located inside the first grille 200, or the insertion slot 230 can be the gap between the first grille 200 and the first panel 110, so that the insertion piece 320 of the second grille 300 can be inserted between the first grille 200 and the first panel 110.

[0072] When assembling the housing 100 assembly, the first grille 200 can be installed on the front side of the first panel 110, such that at least a portion of the first grille 200 can cover the air outlet 111 of the first panel 110, thereby allowing the air outlet direction to be adjusted and changed via the first grille 200. The second grille 300 is installed on the front side of the second panel 120, so that the first grille 200 and the second grille 300 are located in the same plane. This separate installation of the first grille 200 and the second grille 300 reduces the overall size and installation difficulty of the grilles, thus simplifying the process of installing the grilles onto the housing 100.

[0073] Reference Figure 1 , Figure 3 and Figure 4 In some possible implementations, the grille may be provided with at least one snap-fit ​​element, and the panel may be provided with at least one mating element. The snap-fit ​​element and the mating element are provided correspondingly, and the snap-fit ​​element can snap and engage with the corresponding mating element.

[0074] For example, the first grille 200 may be provided with at least one first snap-fit ​​member 220, and the first panel 110 may be provided with at least one first mating member 112.

[0075] In some possible implementations, the number of first mating parts 112 in the first panel 110 can be multiple, and at least some of the multiple first mating parts 112 can be arranged around the air outlet 111.

[0076] For example, multiple first mating parts 112 can be connected to multiple first snap-fit ​​parts 220, so that the first grille 200 can be connected to the first panel 110 near the air outlet 111, so that when the air outlet 111 blows air toward the first grille 200, the first grille 200 will not detach from the first panel 110, making the connection between the first grille 200 and the first panel 110 more stable.

[0077] The number of first snap-fit ​​pieces 220 can be the same as the number of first mating pieces 112. The first snap-fit ​​pieces 220 and the first mating pieces 112 are set in correspondence. The first snap-fit ​​pieces 220 can snap-fit ​​with the corresponding first mating pieces 112, making the connection between the first grille 200 and the first panel 110 more stable.

[0078] In some possible implementations, the first mating member 112 may be provided with a first mating groove, which may extend along a first direction. The first direction may be set to a vertical direction and may be parallel to the height direction of the housing 100.

[0079] The first snap-fit ​​member 220 may include a first connecting portion 222 and a first snap-fit ​​portion 221 connected to each other. The first grille 200 is movable relative to the first panel 110 along a first direction, the first snap-fit ​​portion 221 passes through the first mating groove, and the first connecting portion 222 abuts against the first mating member 112.

[0080] Alternatively, the first mating groove can extend along a second direction. The second direction can be set to a horizontal direction, or it can be set perpendicular to the height direction of the housing 100.

[0081] The first snap-fit ​​member 220 may include a first connecting portion 222 and a first snap-fit ​​portion 221 connected to each other. The first grille 200 is movable relative to the first panel 110 along a second direction. The first snap-fit ​​portion 221 passes through the first mating groove, and the first connecting portion 222 abuts against the first mating member 112.

[0082] By adopting the above technical solution, when the first grille 200 is connected to the first panel 110, the first grille 200 can be moved relative to the first panel 110 along the first direction or the second direction, so that the first snap-fit ​​portion 221 of the plurality of first snap-fit ​​members 220 can be inserted into the first mating groove of the corresponding first mating member 112, thereby making the first grille 200 relatively fixed with the first panel 110, and making the connection between the first grille 200 and the first panel 110 more convenient.

[0083] Reference Figure 1 , Figure 5 and Figure 6 In some possible implementations, the second grille 300 may be provided with at least one second snap-fit ​​member 310, and the second panel 120 may be provided with at least one second mating member 121. For example, the number of second mating members 121 in the second panel 120 may be multiple.

[0084] For example, multiple second mating parts 121 can be connected to multiple second snap-fit ​​parts 310, and the second grille 300 will not detach from the second panel 120, making the connection between the second grille 300 and the second panel 120 more stable.

[0085] The number of second snap-fit ​​pieces 310 can be the same as the number of second mating pieces 121. The second snap-fit ​​pieces 310 and the second mating pieces 121 are set accordingly. The second snap-fit ​​pieces 310 can snap-fit ​​with the corresponding second mating pieces 121, making the connection between the second grille 300 and the second panel 120 more stable.

[0086] In some possible implementations, the second mating member 121 may be provided with a second mating groove, which may extend along a second direction.

[0087] The second direction can be set to a horizontal direction, or it can be set perpendicular to the first direction. Alternatively, the second direction can be set perpendicular to the height direction of the housing 100.

[0088] The second snap-fit ​​member 310 may include a second connecting portion and a second snap-fit ​​portion connected together. The second grille 300 is movable relative to the second panel 120 along a second direction, the second snap-fit ​​portion passes through the second mating groove, and the second connecting portion abuts against the second mating member 121.

[0089] Alternatively, the second mating groove may extend along the first direction.

[0090] The second snap-fit ​​member 310 may include a second connecting portion and a second snap-fit ​​portion connected together. The second grille 300 is movable relative to the second panel 120 along a first direction, the second snap-fit ​​portion passes through the second mating groove, and the second connecting portion abuts against the second mating member 121.

[0091] By adopting the above technical solution, when the second grille 300 is connected to the second panel 120, the second grille 300 can be moved relative to the second panel 120 along the second direction or the first direction, so that the second snap-fit ​​portion of the plurality of second snap-fit ​​members 310 can be inserted into the second mating groove of the corresponding second mating member 121, thereby making the second grille 300 relatively fixed with the second panel 120, and making the connection between the second grille 300 and the second panel 120 more convenient.

[0092] In other words, when the first grille 200 and the second grille 300 are respectively installed on the housing 100, the first grille 200 can be moved along the first direction relative to the first panel 110 of the housing 100 and installed on the first panel 110, and the second grille 300 can be moved along the second direction relative to the second panel 120 of the housing 100 and installed on the second panel 120, so that the first grille 200 and the second grille 300 can be respectively installed on the housing 100, making the installation process of the first grille 200 and the second grille 300 more convenient.

[0093] In some possible implementations, the first panel 110 and the second panel 120 may be arranged along a second direction, the first grille 200 and the second grille 300 may be arranged side by side along the second direction, and when the second grille 300 is fixed to the second panel 120, the second grille 300 may approach the first panel 110 along the second direction, and the second connecting portion abuts against the side of the second mating member 121 away from the first panel 110.

[0094] By adopting the above technical solution, when the second grille 300 is connected to the second panel 120, the second grille 300 can be moved relative to the second panel 120 along the second direction, so that the second snap-fit ​​portion of the plurality of second snap-fit ​​members 310 can be inserted into the second mating groove of the corresponding second mating member 121, and the plug-in member 320 is inserted into the plug-in groove 230 along the second direction, so that the second grille 300 can be fixed to the second panel 120 through the second snap-fit ​​member 310 and the second mating member 121, and the second grille 300 can be fixed to the first grille 200 through the plug-in member 320 and the plug-in groove 230, thereby realizing the installation process of the second grille 300.

[0095] Reference Figure 3 and Figure 6 In some possible implementations, at least one of the first grille 200 and the second grille 300 is provided with a removable mounting base 600. The housing 100 is provided with fasteners that pass through the housing 100 and are threadedly connected to the mounting base 600.

[0096] For example, the mounting base 600 can be configured as a first mounting base 600, which can be disposed in the first grille 200. The first mounting base 600 can be inserted into the air guide 210 of the first grille 200 and fixed to the first grille 200, thereby realizing the installation process of the first mounting base 600.

[0097] When fixing the first grille 200 to the first panel 110, fasteners can be inserted through the housing 100 so that the fasteners can be threadedly connected to the first mounting base 600, thereby making the connection between the first grille 200 and the housing 100 more stable and reducing the possibility of the first grille 200 detaching from the first panel 110.

[0098] For example, the mounting base 600 can be configured as a second mounting base 600, which can be disposed in the second grille 300. The second mounting base 600 can be inserted into the air guide 210 of the second grille 300 and fixed to the second grille 300, thereby realizing the installation process of the second mounting base 600.

[0099] When fixing the second grille 300 to the second panel 120, fasteners can be inserted through the housing 100 so that the fasteners can be threadedly connected to the second mounting base 600, thereby making the connection between the second grille 300 and the housing 100 more stable and reducing the possibility of the second grille 300 detaching from the second panel 120.

[0100] In summary, the housing 100 assembly, by providing a cooperating first grille 200 and second grille 300, such that the first grille 200 and second grille 300 are respectively disposed on the first panel 110 and the second panel 120 of the housing 100, and the first grille 200 and second grille 300 are located in the same plane, allows the first grille 200 and second grille 300 to be processed and manufactured separately, thereby reducing the processing difficulty of the first grille 200 and second grille 300.

[0101] When assembling the housing 100 assembly, the first grille 200 can be installed on the front side of the first panel 110, such that at least a portion of the first grille 200 can cover the air outlet 111 of the first panel 110, thereby allowing the air outlet direction to be adjusted and changed via the first grille 200. The second grille 300 is installed on the front side of the second panel 120, so that the first grille 200 and the second grille 300 are located in the same plane. This separate installation of the first grille 200 and the second grille 300 reduces the overall size and installation difficulty of the grilles, thus simplifying the process of installing the grilles onto the housing 100.

[0102] Secondly, this application provides a household appliance including the housing 100 assembly described in any of the above embodiments. The housing 100 assembly may be provided with a partition to divide the housing 100 assembly into two chambers. The first chamber may be used to accommodate a heat exchange module, such as a fan, and the second chamber may be used to accommodate a power module, such as a compressor.
